resources are of high concern. Their unique behavior under shear loading first was recognised
during oil resources investigations in the Persian Gulf. Off-shore structures have been placed on
carbonate soils which are highly crushable.During storms cyclic loading imposes on the bases of
structures lied down on seabed. Cyclic loading, therefore, may trigger liquefaction phenomenon
which leads to soil collapse and a catostrophic event. Therefore, stability of these expensive
structures need to be investigated. To this aim carbonate sand in medium dense to medium dense
state was considered and its response under varied cyclic shear stress ratio was studied.5463http://ijce.iust.ac.ir/browse.php?a_code=A-10-668-55&slc_lang=en&sid=1H.Salehzadeh180031947532846005934180031947532846005934Yes
